Central Boiler's NEW Forge Outdoor Coal Furnace can be the perfect choice for those that live in Central Ohio where coal is abundant and available. Built with the same quality and attention to detail as Central Boiler's outdoor wood furnaces, the Forge is a better way to heat with coal.

Heat Multiple Buildings - Heating multiple buildings is easy. The Forge 1500 has one set of 1-1/4” supply and return ports (that can be configured for two pumps). The Forge 3500 has one set of 1-1/4” supply and return ports and one set of 3/4” supply and return ports. The Forge 6000 has one set of 1-1/4” supply and return ports and two sets of 3/4” supply and return ports.

Convenient Operation - Loading coal is easy with the large firebox door. Ergonomically designed, the firebox door is insulated and easy to open and close. Heavy-duty shaker grate, conveniently operated by handle on side of the furnace, allows ash to fall below into the ash collection area. Ash removal is easy.

Burn Less Coal - A hallmark of Central Boiler furnaces for over 30 years, spray-on urethane is the ultimate airtight, waterproof insulation that locks the heat in to reduce coal usage, even at temperatures of -35˚F or colder. It provides 2-3 times the effective R-value of conventional fiberglass batt insulation.

Ultimate Control - The FireStar™ II electronic controller monitors all functions of the furnace and can store and share operational data. The controller’s technology optimizes the combustion process by automatically adjusting the fan-forced air for a cleaner and more efficient burn. Compatible with the FireStar XP wi-fi module.
